The July 20th meeting of the Peninsula Users Group will 
be given over to a swap meet to which seabers and foreer 
geabers of all three Bay Area Timex/Sinclair Users Groups 
will be invited. 

Following a suggestion by Russ English and other seabers 
of EBZUG, the Peninsula Group discussed and agreed to the 
proposal at its May seeting. It was also agreed that the June 
and July issues of TIMELINEZ would go to an expanded sailing 
list that would include former members of ail three groups 
who aay have T/S items they wish to dispose of. 

Be sure and reaind anyone who sight be interested of 
this event. It will get under way at 1:00 P.M., duly 20th in 
the Sierra Room at Peninsula Hospital in Burlingame (see sap 
elsewhere in this issue). 


Also at the May PUG aeeting: 

Jack Dohany has an AERCO CPM terainal connected to Ay 
2068 for demonstration purposes. He was unable to bring i 
to the aeeting, but would be happy to talk with anybody about 
it or show it to those who care to drop by his house. Call 
for an appointaent. 

Rex Lundgren, who has been doing 1000 and 2068 repairs 
for Sunset Electronics, reports that acst of the probleas he 
is seeing are caused by careless attacheent and removal of 
peripherals. Rex reminds everyone to be sure all power is off 
before removing or attaching peripherals. Particular care 
should be taken with those devices which use a blob of solder 
as a locating key for the edge-connector. The solder is a 
conducter and is also very soft and so is easily deformed or 
displaced, which may cause the two connectors to sis-sate 
(Imagine the trouble THAT can cause‘). 

1 showed some pictures that had been downloaded fros 
CompuServe in the Run-Length-Encoded format and then been 
decoded and printed by ay GL computer. See ay article 
elsewhere in this issue. | 

George Nockridge received a letter from attorneys for a 
company aarketing a software line called ‘TINE LINE.’ The 
letter asks us to cease and desist infringing on their trade 
mark with our nase ’TIMELINEZ.’ 

Pat Morrissey has found an attorney for us who is 
handling the case ‘pro bono’ (free), and who says we are 
probably safe on grounds of prior use. If we wanted to he 
nasty we eight even collect royalties from THEM’ 

See you at the next PUG meeting, Sunday June ® 15.

USING TIME ¢(*>) DOING TIME 
or TIME WELL SPENT 


by Rita A. Toth 


In July of 1982, George Mockridge, President of the Peninsula 
User Group (PUG), responded to a letter he received from Robert 
Rhodes, the first prisoner in the Nevada State Prison to be 
granted permission to buy a computer. Robert had purchased a 
Sinclair ZX-81 which included an issue of SYNTAX newsletter in 
which he found George’s address. 


In a stream of on-going letters, Robert told how his interest in 
computers developed when he realized his propensity for learning 
programming while taking correspondence courses in the subject. 
Since he was sharing the ZX-81 and his limited knowledge with 
other interested prisoners, he realized that they needed to cor- 
respond with someone who could provide support and answer ques- 
tions. Consequently, since July 1982, George and PUG have sent 
much material dealing with specific questions from the prisoners 
as well as general information about computers, printers, tapes 
and programming. 


In November of 1982, Robert transferred to the Southern Desert 

Correctional Center (SDCC) in Indian Springs, Nevada. At SDCC, 
he continued his studies in computers and was again able to in- 
terest some of the other prisoners to learn programming. 


In June of 1985, the National Education Corporation donated a 
Computer Literacy Programming Course to SDCC. This course con~ 
sists of a TS-1500, a recorder and eleven course books in BASIC 
programming. Needless to say, many of the prisoners have signed 
up because they realize that the equipment allows them a unique 
opportunity to learn about programming and computers. 


Having learned programming on T/S equipment, the immates were 
able to transfer their knowledge to a KAYPRO II. (This larger 
computer was donated to SDCC from a source other than PUG in the 
latter part of 1985.) Using the KAYPRO II, they were able to 
computerize the Parole and Probation Office in which they worked 
and they told us that their program will eventually be used in 
Data Recording Keeping Offices throughout the State of Nevada. 


In January of 1986, George Mockridge asked me to assume the 
duties of liaison with this activity. 


The following are a few excerpts from a recent letter that PUG 
received trom one of the prisoners. I’d like to share his 
thoughts and information with you: 


"I am currently involved in teaching our "Re-Entry’” 
course here at the prison (SDCC). It accommodates 
about 30 to 40 professional people who come in and 





IMELINE | C2 


instruct inmates in various fields prior to their 
release into the community. One of the courses is 

a course given by a Systems Analyst for the City of 
las Vegas, who has assured me that he will provide 
several jobs to inmates who have medium range program- 
ming abilities. He is also trying to formulate jobs 
within the institution for those of us old timers who 
may be around awhile. See what you guys started?!%?! 
sensational stuff, to say the least." 


"George has quite a reputation in the yard now. His 
help and the help of the User Group is something that 
gets through the grapevine pretty quick. 1 doubt very 
seriously if you guys really know how deeply we really 
appreciate the help you have extended.” 


"You guys would laugh vourselves sick if you could see 
these big old convicts hunched over one of those 1000’s 
Punching in data. Its such a treat to see men using 
their minds instead of their fists in here. A small 
wonderful light in a very violent environment. We do 
appreciate you folks so much. I doubt if you will ever 
know how much. ” 


Because SO many more prisoners are interested in learning about 
computers and programming and because their equipment is limited, 
it would be helpful if TIMELINEZ readers would send donations of 
equipment, tapes, books, magazines, printers, etc.. (They are 
particularly interested in obtaining a TS-2068.) Note that such 


donations are tax deductible. Be sure to include a note giving 
the fair market value of the donation. Send donations to; 


Mr. William J. Kassel, Pre-Release Supervisor 
Nevada Department of Parole and Probation 
Mailroom Complex 

215 E. Bonanza Street 

Las Vegas, Nevada 89158 (702) 386-5150 


or call: 
Rita Toth, SDCC Liaison 
(415) 3928-49367 


I can arrange to send the items for you but you decide the fair 
market value. 


IMPORTANT! Because prisoners are not allowed tools, donations 
must be in good working order or they will be disposed of because 
the prison cannot afford to return non-working items. 


All User Groups are invited to participate in this program. I 
will try to keep you informed of our progress through future 
TIMELINEZ articles.

“DECODING COMPUSERVE’? S&S 


RUN —-LENGTH-ENCODED GRAPHIC’ &S 
ON THE SINCLATR QL 
by Norm Lehfeldt 
KHKKKKKKKKEKHEKKKKEK HERE EK HAKKAR IER ERIK SESSA EAE 


' have been intrigued by CoapuServe’s ’Run Length 
Encoded’ graphics for some time. |] knew that using this 
system, owners of the acst popular coaputers could view and 
download pictures of participants on the Citizens Band Radio 
Sisulator, pictures of the FB!’s ten-aost-wanted desperadces, 
the National Weather Service’s radar weather saps and siailar 
graphic delights. The new Picture Support Forum, in 
particular, offers a dazzling selection of computer graphics 
and digitized photographs. But until now, I had not been able 
to learn enough about the encoding system tobe able to 
decode the pictures with any of the Sinclair computers. 

Briefly stated, run length encoding is a sethod of 
translating a screen display into a string of ASCII 
characters so that it aay be transmitted and displayed among 
dis-similar computers. CompuServe subscribers may read a 
fuller explanation of the method in the file headed 
"RLEDEC. TXT’ in DL2 of the CBIS interest group on the systes. 

The accompanying short program wil! allow off-line 
display of the pictures cn the QL. The pictures may be 
printed using a utility such as ’QDUMPS.’

Some notes cn using the progras: 


The graphics files aust first be LOSged to sicrodrive 
using the QCODE terainal prograg. Take care to LOG as few 
extraneous characters before and after the file as possible. 

Boot your QL in the Monitor gsode (Fi at the copyright 
prompt). LRUN this prograa. It formats the screen so that it 
should work on TY’s that don’t have too auch over-scan. 

At the prompt enter the exact naae under which you have 
legged the graphic file you wish to display. The cartridge 
containing your graphics files aust be in sicrodrive 2. The 
computer may take several ainutes to draw the picture, 
depending on how auch detail it contains. 

When you are through looking at the picture, pressing 
any key clears the screen and prompts you for a new file 


name. 


Note that you can change the INK and PAPER colors by 
altering line 190. Changine line 120 to ’MQDE 8’ so that you 
can have more colors will work except that a difference in 
the screen mapping will produce some errors in the di splayeg 
picture. 

For some reason, the OL sometimes returns a control code 
to the data stream when accessing the sicrodrive. This 
distorts all of the picture which follows. Line 230 traps 
this error, but a gore elegant solution is solicited. 

Let me know what you think of this and please share any 
improvements you sake te it. 


It looks fairly easy to write a program to decode these 
pictures for the 2048. I intend to try to find tiae to do it, 
but if you manage it first, please send it in for 
publication.
